Antarctica, known as the seventh continent, is the last to be discovered on Earth and the only one without permanent human settlement. It lies at the convergence of the Pacific, Indian, and Atlantic Oceans, with ten million square kilometers of frozen tundra and ice fields, extreme ecological conditions, scarce resources for survival, and situated on the Earth's magnetic pole, making it an undeveloped land to this day.
One day, a massive flying craft skimmed over the glacier. Due to the abundant reflection of light and the abrupt changes in the magnetic field, flying at such speed over Antarctica is extremely dangerous, but this aircraft seemed indifferent to those risks. It hurtled toward a gigantic glacier with a velocity that seemed to defy its size, then crashed straight into it.
